DESCRIPTION
The AIC1848 charge pump is a micropower charge pump DC/DC converter that produces a regulated output voltage from 2.7V to 4.5V input voltage. Low external-part count (one flying capacitor and two small bypass capacitors) makes the AIC1848 ideal for small, batterypowered applications. The AIC1848 operates as a constant frequency mode switched capacitor voltage doubler to
